Terrifying Video: Mum And Baby In Buggy Could Have Drowned In Freezing Sea

This is the moment a struggling mother could have drowned with her baby after slipping into the freezing sea while crossing a dangerous causeway with a buggy.

The dramatic video shows the terrified mum and her helpless baby as they were almost swept away by a rapidly rising tide.

The young mother is shown losing her footing while pushing her child in a buggy across a causeway in the Firth of Forth.

Both the woman and the pram were submerged in the water before onlookers rushed to their aid.

A shocked passer-by captured the dramatic incident along the narrow link between Scotland's Cramond island in the Firth of Forth and the mainland, and posted it on YouTube.

Walkers can access the island at low tide but because the water rises quickly people are often stranded.

RNLI boss Tom Robertson said: "One of the main problems we have is something like 80 per cent of the people who have been involved in these kinds of incidents are not of British extraction, so maybe they can't read the warning notices.

"This incident certainly could have been tragic if someone hadn't managed to get to the child quickly.

"There have been many, many incidents in the past at Cramond. People get in to trouble on the island or on the causeway about 20 times a year.

"Thankfully, nobody has lost their life but there have been people who have had to be treated for hypothermia."
